Maximizing Efficiency in Biogas Production: A Comprehensive Review of Operational Parameters

This review provides a comprehensive overview of the key operational parameters essential for efficient biogas production through anaerobic digestion. The article emphasizes the crucial role of selecting an appropriate anaerobic reactor type and configuration based on factors such as feedstock, biogas yield requirements, and operational costs. In addition, the review highlights the significance of start-up and acclimation stages, optimal pH and temperature conditions, volatile fatty acid (VFA) concentration, and maintaining stable pH levels and buffering capacity to enhance the efficiency of biogas production. Furthermore, organic loading rate, feedstock quality, hydraulic retention time, methane yield, and biogas composition are also critical parameters that require careful monitoring and control for the optimization of the biogas production process. Proper optimization of these parameters can lead to enhanced local energy production, diversify the energy mix, and reduce dependence on fossil fuels, thereby contributing to enhanced energy security. Overall, the review underscores the importance of considering all operational parameters and their interdependence to achieve optimal results in biogas production.
